FINDING FOR GLASPS Application filed October 28, 1931. SerialNo.-571,492.

This invention relates to new and useful improvements in a finding for aclasp.

The invention relates particularly to a finding which is composed of abacking member pivotally connected with a jaw member,

means for urging said members together, and

a stop for limiting closing of the members about said pivot.

In the trade, it is the custom to solder finding members upon the backsof ornamental members and the provisionof the stop for preventingclosing of the members causes the condition in which the backing membermay be rested fiat against the back of the ornament and readily solderedon. In practice, it is found quite often thebacking members do not restfiat against the back of the ornamental member. The cause of this may bea slightly bent ornamental member .or jaw member on the finding. It isan object of this invention to construct a stop which is resilient so asto allow a certain amount of forced relative movements between thebacking member and the aw member to provide for the backing memberassuming a flat position against the back of the ornament. Thisfacilitates the soldering.

As another object of this invention it is proposed to locate the stop ofthe finding in 3 a manner so that the finding may be manufactured at aminimum cost.

As a still further object of this invention it is proposed to constructthe means for urging the members together in the form of a fiat springand to mount the stop upon the spring in a manner so that the jaw memberis limited to close to a position substantially parallel with the flatspring, and in turn, the fiat spring carry the bac ring member so thatit is substantially parallel to the spring.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descripti onand accompanying drawings, and to the appended claims in which thevarious novel features of theinvention are more par ticularly set forth.

In the accompanying drawings forming a material part of this disclosureFig. 1 is a perspective View of a finding 5o constructed according tothis invention.

Fig. 2 is a perspective view of the finding shown in Fig. 1 viewed fromthe back.

Fig. 3 is a fragmentary sectional view taken on the line 3-8 of Fig. 1.

The finding consists ofa backing member 10 pivotally connected with ajaw member 11. The backing member 10 is stamped from sheet material andis formed with side lugs 12 adapted to receive small projections 13 onon the sides ofthe jaw member 11. The jaw member is formed with severalprongs 14 for engaging against the back of an ornament to clamp theornament upon clothing. I

A neans is provided forurging the back member and jaw member. together.This means consistsof a fiat spring 15 located between the backingmember and the jaw member.

The ends of the spring 15 are formed with cutouts 16 producing prongs 17engaging on opposite sides of a reduced neck 18 connecting the lugs 12with the backing member. The prongs 17 thus hold the backing member 10substantially parallel with the spring.

he spring 15' is of a slightly greater length than the distance betweenthe reduced portions 18 of the backing member so as to be arched awayfrom the backing member as clearly shown in Fig.1.

The rear end of the jaw member 11 is formed with an upturned lip 19engaging against the bottom rear edge of the spring 15. This lip isformed curved so as to allow opening of the jaw member 11 relative tothe 35 backing member by reason of bowing the spring 15 upwards. In theclosed position of the finding, the spring 15 presses downwards on thelip 19 so as to cause the main portion of the jaw member to tend to move9 towards the backing member 15. A finger 20 projects from the edge ofthe spring 15 which is opposite the lip 19 and is directed down againstthe jaw member 11. Consequently, as the spring 15 tends to pivot the jawmember 11 towards the backing member 10, the parts will be arrested andassume positions in which the backing member 10 is substantiallyparallel to the jaw member 11.

The arrangement of the stop member 20 upon the spring has severaldistinct advantages. One advantage is that the backing member 10 isresiliently held relative to the jaw member 11. This allows rocking ofthe backing member relative to the jaw member within limits which doesnot cause the open ing of the finding. Such rocking provides for theproper fitting of the backing memher on the rear of the ornament. Asecond advantage in the location of the stop finger on the spring isthatthe finding may thus be manufactured at a cheaper price than if thestop fingerwere located on eitherthe backing member or the aw member.This is so in that the backing member and the jaw memberiscommerciallyformed of German silver of a gauge approximately .025 of aninch and the spring is formed from high carbon steel approximately .012of an inch. The cost of the German silver is materially higher than thecost of the steel. Since the stop is located upon the spring and not thejaw or backing member, less material is needed on the jaw and backingmembers. More than this, since the stop is located on the spring, it isof a smaller size than if located either on the backing member or jawmember and acting against the other.

While I have illustrated and described my invention with some degree ofparticularity, I realize that in practice various alterations thereinmay be made. I therefore reserve the right and privilege of changing theform of the details of construction or otherwise altering thearrangement of the correlated parts without departing from the spirit orthe scope of the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent is 1. In a finding for clasps, abacking member, a jaw member pivotally connected with the backingmember, a lip on one of said members near the pivot, a fiat spring bowedbetween said lip and the other member and fixedly connected with thesaid member to close the front ends of said members and extending to theother side of said pivot, and a finger projecting from thelatter-mentioned side of said flat spring and engageable against themember formed with the lip I to limit pivoting of the member to aposition v substantially parallel to the spring.
